Application filed May 19,

This invention relates to a heater for paper making machines and is designed more especially as an improvement upon the well known Hollander and Tait types of beaters. It has been the practice heretofore to utilize, in connection with the beater 'roll a relatively narrow concave formed of blades cooperating with the blades on the roll whereby the stock is broken up and subsequently raised over a backfall into a trough in which the stock is circulated. These old types of beaters have been found objectionable, however, because of the small size of the concave, the. lack of convenient adjustment of the concave, and the-necessity of subjecting the stock repeatedly to the action of the same beater. I

It is an object of the present invention to provide a beater the concave of which is extended through a much wider angle than has heretofore been possible, means being employed whereby this concave can be quickly and accurately adjusted relative to the roll to compensate for wear upon the blades and to regulate the action of the cooperating part s."

A further object is to provide a beater so constructed thatthe stock, after being acted upon by the cooperating blades of the roll and concave,'will be expelled and guided to another beater instead of being delivered over a backfall and returned to the same beater.

\Vith the foregoingand other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein'disclosed may be made within the scope of what is claimed, without departingfrom the spirit of the invention.

In the accompan ing drawings, the preferred form of t e invention has been shown. a

In said drawings,

Figure 1 is an end elevation of the beater showing the pipes for feeding stock to and from the same, a portion of another beater being shown connected thereto. 1 I

Figure 2 is a top plan View.

Figure 3 is a section on line 3-3, Figure 2.

Figure 4: is a section on line 4--4, Figure 3.

Referring to the figures by characters of reference 1 designates a housing one wall of 1927. Serial No. 192,754.

which is smooth and concave as shown at 2 while arranged opposite this wall within the housingis a slide 3 the base portion of which has an extension or ton ue 4 slidablewithin a recess 5 in the housing. Slide 3 constitutes an adjustable concave, its exposed face being concave as shown at (land provided with parallel grooves 7in which are seated edges of parallel stationary blades 8. These blades can beproperly spaced by filler strips 9 arranged therebetween and bearing against the concave surface 6 of the slide.

Adjustable bearings 10 are provided at the sides of the, housing 1 and j'ourn aled in these bearings is a shaft 11 extending through slots 12 in the sides of the housing. To this shaft are secured the heads 13 and one or more intermediate disks 14 of the beater roll,

the peripheries of these heads and disks be-' ing notched as at 15 to receive the inner edges of the blades 16 of the beater roll.

These blades are properly spaced by bars 17 fitted snugly therebetween and connected to th heads and disks.

Mounted on the housing l'at a point remote from the slide 3 is an outlet box 18 the top of which is extended over the beater roll to provide a hood 19, one end of this hood being attached to acover plate 20 secured to the housing and overhanging the slide 3. A delivery pipe or flue 21 extends laterally and downwardly from one side of the box 18. A feed pipe or flue 22 opens into the housing 1 below the box 18 and above theconcave wall 2. This feed pipe 22 is used for delive ering stock to the first beater of a battery made up of several heaters .but the outlet pipe or flue 21 of each beater constitutes the feed pipe or flue of the next adjoining beater. Thus it will be seen that stock after being admitted to the housing of the first beater of a battery from pipe or flue 22 will be discharged from said housing to the pipe or flue 21 thereof and conveyed thereby to the housing of the next beater of the battery.

housing 1. In the structure illustrated the outer ends of these screws support a frame 24 and have gears 25.

These gears mesh with gears 26 secured to a shaft 27 jour naled in the frame. Any suitable means, such as a hand wheel 28, is provided for rotating the shaft and during such rotation the gears will cause the screws to feed simultaneously to move slide 3 toward or from the beater roll. Thus the blades 8 can be minutely adjusted relative to the blades 16.

When the stock'is admitted to the housing 1 from the pipe or flue 22 it will be carried downwardly along the smooth concave wall and he broken up by the blades 8 and 16. Thereafter the stock will be expelled into the hood 19 and box 18 and pass outwardly through the pipe or fine 21 into the housing 1 of the next adjoining beater roll.

' Any desired adjustment of the shaft 11 can be etfected readily by shifting the bearings 10. It is to be understood of course that the different blades can be easily removed or repaired and others substituted therefor whenever desired this being done in the same manner as heretofore and this is well known to those skilled in the art.

What is claimed is:

1. A heater for paper making machines including a housing,v a concave slidably mounted therein, means for adjusting the concave, said housing having a fixed concave wall, and a beater roll mounted for rotation between said wall and the adjustable concave.

2 A heater for paper making machines including a housing having a stationary concave wall, a concave slidable within the housing and disposed opposite said wall,

' parallel blades carried by the slidable concave, means for adjusting the slidable concave toward and from said concave wall, and a beater roll mounted for rotation between said wall and the adjustable concave.

point beneath the roll to the top of the hous--' ing, an outlet box, and a hood extending over the roll for directing stock from the concave to the outlet box.

4. A beater for paper making machines including a housing, for rotation therein, a concave in the housing and extending longitudinally of the roll, said concave extending from a point beneath the roll to the top of the housing, and means for adjusting the concave toward and from the roll.

5. A heater for paper making machines including a housing, a beater roll mounted for rotation therein, a concave in the housing and extending longitudinally of the roll, said concave extending from a oint beneath the roll to the top of the houslng, an outlet box, means for directing stock from the upper portion of the concave over the roll to the outlet box, and means for feeding stock into thehousing below the outlet box.

6. In a paper machine a plurality of housings, a concave in each housing extending from the bottom portion to the top portion thereof, a heater roll in each housing cooperating with the concave,v an outlet box upon each housing, means for directing stock from the upper portion of each concave over its roll to the outlet box, there being a stock inlet below each outlet box, and means for conducting stock from each outlet box to the inlet of the next adjoining housing.

lntestimony that I claim the foregoing as my own,-I have hereto 'atfixed my signature.
